Speaking about comments that QI creator John Lloyd made - in which he admitted that he had wanted the series to be "world-changing" - Davies suggested that the program will have "quite a strong legacy".

"As far as it being world-changing, it would help if they could show it in America," he continued. "But they're not allowed to show it in America because they can't get clearance on all the images that are used in the background.

"It's one of the most ridiculous things I've come across yet in my career. There's no way of coming to some agreement - image by image they have to clear it and pay someone."

Davies also revealed that the images have been a problem in the UK, saying: "I know budget cuts in recent years have made it harder to get the ones they want so they do now have to use ones mostly that are free. But that's always been the obstacle to it being shown in the States."

The comedian's new show, Alan Davies: As Yet Untitled, begins on Dave tomorrow (June 16) at 10pm on Dave.
